Main display of conventional portable communication device is too small to display the webpage, such that the user has to move the webpage continuously, it is inconvenient to the user. The present invention includes a detecting unit 104 which may detect whether internet is connected or not. If an internet package or signal is detected or the browser is activated, the control unit activates a switch device 102 and transfer internet signal or all or part of the information to the extension display 185 to drive the extension display 185 to display all or part of the information, whereby facilitating to display the webpage information. Display area of aforementioned extension display 185 is greater than the one of the main display, and the user can determine whether the display is switched or not. In the case, the cellular 10 may drive the main display and the extension display at the same time. In the type of built-in extension display, it may comprise a receiving device 188 to receive the extension display 185. Take a flexible display as an example, such as OLED display, it can be rolled and received in a storage space, and can be drawn back to spread out the display. Aforementioned OLED (Organic Light-Emitting Diode) is also called OLED (Organic Electroluminesence Display).

Aforementioned detecting unit 104 which can be a single circuit or an integrated circuit may obtain parameters directly or indirectly. Messages received by the communication device of the present invention can transfer all or part of webpage information manually or automatically to the extension display 185 by the switch device 102 to browse the webpage.

Other embodiments are similar to aforementioned embodiments, and the difference is described as follows. When the detecting unit 104 detects video or dynamic, still image signals, such as video format, photo format, digital TV signals or MPEG signals, the control unit 100 activates the switch device 102 to switch video signals to the extension display 185. For example, a commercialized processor which can process and decode the compressed MPEG file may be introduced, such as a media player chip having H.264 codec engine. For example, the processing chip is composed by a CPU core, a media engine, a graphics processor, and a virtual mobile engine (VME). The CPU core is based on the design of R4000 of MIPS, and comprises a floating point processor (FPU) and a vector floating point processor (VFPU), such that the ability of floating point computing can reach more than 2.6 GFlops per second; the media engine can use R4000 which is an identical one used in the CPU core, and includes an independent embedded 2 MB memory to assist the system to process audio/video stream. Thus, an embedded memory which can control the process of processing information by programming is introduced to adapt to the vector process unit including H.264 decompression, and various process demands such as audio process. And the utilization rate of the process unit may be improved by design of altering information process dynamically, thereby simplifying design of the chip and reducing lost of power.
